Doubt regarding excess leave period

Hi freinds,i have a doubt regarding articleship period.Actually i had taken transfer in jan 2008 and i received a letter from institute in which they wrote that you have taken 1 day excess leave with your previous employer.Now my articleship period ends on 26 April with current employer,so do i have to write completion date in form 108 as 27 April or 26 April?? 26th April is written on letter and also on student details in Institute website.Please reply...Thanks
